Chiropractor&rsquo;s biggest victory came in the Hollywood Derby in November 2015, when he edged March by a head to win the Grade 1 event in his graded stakes debut. However, the gelding has not finished on the board since then, with his losing streak stretching to seven as he finished sixth in an optional&#45;claiming event last Saturday on the Saratoga turf. According to Craig Bernick, president of owner Glen Hill Farm, that may have been the penultimate start of Chiropractor&rsquo;s career. &ldquo;Chiropractor didn&rsquo;t handle the footing at all,&rdquo; Bernick said via his social media accounts. &ldquo;Will try him one more time on firmer ground, and if he doesn&rsquo;t run well, can retire at Glen Hill Farm.&rdquo;Chiropractor, a 5&#45;year&#45;old son of leading turf sire Kitten&rsquo;s Joy, runs as a homebred for Glen Hill. He is a half&#45;brother to Grade 1 winner Coil.
